GENERAL DESCRIPTION
The PILOT 1500 HP is a single-phase welding
machine based on inverter technology.

CONTROL
The PILOT 1500 HP machine is mainly designed for
TIG welding, and features functions such as:
- variable slope down
- variable gas post-flow time
- option of 2-times or 4-times operation
- LIFTIG or HF-ignition can be selected
- current control from the TIG torch handle-remote
control facility
- Digital display
The machine is designed also for welding with coated
electrodes and is equipped with Antifreeze function.
In LIFTIG ignition the TIG arc is ignited after making
contact between the workpiece and the tungsten
electrode, after which the trigger is activated and the
arc established by lifting the electrode away from the
workpiece.
In HF ignition the TIG arc is ignited without contact. A
high-frequency (HF) impulse initiates the arc when the
trigger is activated.
Mains connection
After the mains cable has been connected, the
machine is ready for use. Please note that all cable
connections must be made by authorised and qualified
staff.
Connection of welding cables /
Connection of TIG torch
Connect the welding cables to the front of the
REF
machine. Please note that the plug must be turned 45
degrees after insertion into the socket - otherwise the
plug can be damaged due to excessive contact re-
sistance.
Configuration
MIGATRONIC disclaims all responsibility for damaged
cables and other damages related to welding with
under sized welding torch and welding cables
measured by welding specifications e.g. in relation to
permissible load.
Important!
In order to avoid destruction of
plugs and cables, good electric
contact
connecting earth cable and
welding torch to the machine.
Usage of the machine (example)
All data refers to PILOT 1500 HP machines.
When welding with PILOT 1500 HP machines a heat-
ing of various components of the machine takes place
and during breaks these components will cool down
again.
It is not possible to overload the machine in normal
use, and there is no need for cooling down periods at
current settings up to 80 Amps. When the machine is
set for welding currents higher than these, there will be
a need for periods during which the machine can cool
down.
The length of these periods depends on the current
setting, and the machine should not be switched off in
the meantime. If the periods for cooling down during
use of the machine are not sufficiently long, the over-
heating protection will automatically stop the welding
process and the yellow LED will come on.
The yellow LED switches off when the machine has
cooled down sufficiently, and the machine is ready for
welding. Max. load is:
